Simultaneous Equations means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.

Materials: Two simple equation cards; Pencil and scrap paper. 1. Say the goal of Simultaneous Equations in plain words once. 2. Adult solves x+y=5 and x−y=1 by substitution or elimination. 3. Child solves three paired linear systems and checks each pair by substitution. 4. Fresh check: one fresh two-equation system. Record and stop. Done: three correct (x,y) pairs with a check. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.
